摘要

Abstract:(It)-(+)-3-Methylcyclohexanone was converted to the (It)-(-)-5-benzal derivative and this was reduced by use of aluminum chloride-lithium aluminum hydride to a separable mixture of (S)-(+)-1-benzylidene-4-methylcyclohexane and (R)-(+)-4-methyl-l- benzylcyclohexene. The benzalketone and the benzylidenecyclohexane show strong negative Cotton effects, indicating that their chromophores are twisted. The relationship of ...
